RichiH has written a new version of vcsh, a script I use for my keep-all-your-config-files-in-git setup, described here. It’s been discussed a lot recently on the vcs-home mailing list. I’m not switching over because my current setup Works For Me but I thought it was worth linking too; looks like a great way forward.
DVCS-autosync is a cool Dropbox replacement worth checking out too; a different aim to the above though.
